John Kenneth Wetton (June 12, 1949 – January 31, 2017) was an English singer, bassist, and songwriter. He was born in Willington, Derbyshire, and grew up in Bournemouth. He rose to fame with bands Mogul Thrash, Family, King Crimson, Roxy Music/Bryan Ferry, Uriah Heep, and Wishbone Ash.
After his period with King Crimson, Wetton formed UK, and later he was the frontman and principal songwriter of the supergroup Asia, which proved to be his biggest commercial success. Their self-titled debut album sold eight million copies worldwide and was Billboard magazine’s No. 1 album of 1982. He later formed the duo Icon with Geoff Downes (ex-Yes, ex-Buggles), and since the 1990s had a successful solo career releasing a large number of studio and live albums.
Wetton had a long career as an in-demand session bass player, and collaborated with many members of progressive rock bands such as Yes (including Steve Howe, Bill Bruford, Geoff Downes, Alan White, Billy Sherwood and Peter Banks), Roxy Music and Bryan Ferry, and Genesis (Steve Hackett).
